IMPROVEMENT IN BUTTON-HOLE CUTTERS.

Specification forming part of Letters Patent No. 133,708, dated December10, l1872.

To all whom it may concern: Be it known that I, GAMrLLUs M. JOHNSON, ofHartford, in the countyv of Hartford and State of Connecticut, haveinvented certain new and useful Improvements in Button-Hole Cutters; andI do hereby declare that the fol lowing is a full, clear, and exactdescription thereof, whereby a person skilled in the art can make anduse the same, reference being had to the accompanying drawing and to theVletters of referencermarked thereon.

Like letters in the figures indicate the same parts.

`My invention consists in the adaptation of gages to the fra-me for thepurpose of measuring the distance from the edge of the cloth that thebuttonhole is to be cut, and also the distance between the button-holesalong the edge of the cloth.

In the accompanying drawing, Figure I is a front view of my improvedbutton-hole cutf ter; Fig. 2 is a side view of the same; and Fig. 3 isadetached view of a different form of cuttin gtool.

Ais the frame. B is a vertical shaft, which 'carries the cutting-tool. Cis a knob or handle at the top to apply a blow or pressure to thecutter. D is the cutting-tool, which is attached to the shaft B by meansof the thumbscrew E.V F is a `spiral spring for raising the shaft Bafter the button-hole is cut. G is a gage extending back from the frameof thebutton-hole cutter for the purpose of measuring the distancebetween the last hole cut and the intended place for the next. H is agraduated edge upon the frame for the purpose of measuring the distanceof the button-hole about to be cut from the edge of the cloth. Thesegages are, for convenience in use, graduated into inches and fractions.

The operation of my invention is as follows: The thumb-screw E isloosened, and the cutting-edge ofthe length of button-hole desired theedge of the frame at H. The screw E is then tightened and the edge ofthe cutter placed over the desired position. Thev handle out. To out thenext button-hole the desired distance is measured by placing one of thethe graduations of the gage Gr over the last hole cut and placing thesame division of H as ,before on the edge ofthe cloth. This gages theexact position of each successive button-hole as it is cut.

In place-,of the four-sided cutter D I sometimes use a series of cuttersof diierent widths, of the form shown at D', in Fig. 3. These have theadvantage of giving a greater number of widths, all applicable to themachine without removing the screw E. By loosening this, merely, acutter can be slipped under the head and then clamped fast.

What I claim as my invention isframe of a button-hole cutter, whenconstructpurpose described. t 2. The gage H for measuring from the edgeof the clothto the button-hole, in combination with the frame of abutton-hole cutter, substantially as and for the purpose described.CMILLUS M. JOHNSON.
